Abstract
The utility model discloses an anti-pollution outer sleeve for artificial insemination of cows, which comprises a hollow polypropylene pipe body (1); the front end of the polypropylene pipe body (1) is provided with a scratch-proof boss (2); the front half section of the polypropylene pipe body (1) is provided with an anti-skidding boss (3); the outer surfaces of the scratch-proof boss (2) and the anti-skidding boss (3) are in circular arc shapes; and the tail end of the polypropylene pipe body (1) is provided with a semen deposition gun inserting hole (4). The anti-pollution outer sleeve is used for replacing the cleaning and disinfecting of the vulva of the cows, thus avoiding the pollution caused in the artificial insemination process, reducing the occurrence of reproductive system diseases and improving the conception rate of the artificial insemination of the cows. The anti-pollution outer sleeve is simple in structure, easy to manufacture and ideal in using effect.
Description
Technical field
This utility model relates to the livestock reproduction technology, and is especially a kind of for the test-tube anti-pollution overcoat of cattle.
Background technology
At present, the application of technology of artificial insemination has been brought into play important function to China's cattle breeds improvement and cultivation, is an indispensable key technology in the cattle cultivation.Under good feeding and management condition, the cattle non-return rate can reach more than 50%, and a year over-all conception rate can reach more than 85%～90% even 95%.But the artificial insemination misoperation can cause the cows conception rate low and cause reproductive diseases.The cattle technology of artificial insemination in, polluted for fear of spermatic gun, need to draw clean cow rectum place excrement with hands, and before semen deposition first the pudendum to cow carry out cleaning and sterilizing, but, such method is when cleaning pudendum and semen deposition operation, and cow also can defecate pollute pudendum and spermatic gun head; And two kinds of extreme cases of such method existence, a kind of is to cause excessive cleaning and sterilizing, makes disinfectant solution enter vagina, brings the uterus during semen deposition into, and kills sperm; Another kind of then be that the cleaning of pudendum is not enough, during operation feces is brought into vagina, pollute vagina and sperm is caused damage.
Summary of the invention
The purpose of this utility model is: provide that a kind of it can improve the test-tube conception rate of cattle for the test-tube anti-pollution overcoat of cattle, and simplify test-tube operation, reduce the possibility that pollutes in the artificial insemination process, to overcome the deficiencies in the prior art.
This utility model is achieved in that for the test-tube anti-pollution overcoat of cattle, the polypropylene body that comprises hollow, front end at the polypropylene body is provided with anti-scratch boss, first half section at the polypropylene body is provided with anti-skidding boss, and the outer surface of anti-scratch boss and anti-skidding boss is circular arc; End at the polypropylene body is provided with the spermatic gun insert port.Anti-scratch boss is smooth hemispherical, when inserting the cow vagina, can prevent the scratch vagina; Anti-skidding boss is hemispherical, can prevent that anti-pollution overcoat is from the vagina slippage.
The spermatic gun insert port is funnel-form, and the diameter of major part is 2～2.5 cm, and the diameter of osculum is 0.5cm, and the angle of inclination of sidewall is 25～35 °.
The length of polypropylene body is 27～29cm, and the external diameter of polypropylene body is that 0.7cm, its internal diameter are 0.5cm; The spacing of anti-scratch boss and anti-skidding boss is 8～10cm; The external diameter of anti-scratch boss and anti-skidding boss is 0.85cm.
Before the tradition semen deposition, need to draw clean cow rectum place excrement, then cleaning and sterilizing cow pudendum and wiped clean with hands.This operating process is not only loaded down with trivial details, and easily reduces test-tube conception rate, and reason is: (1) when cleaning pudendum and semen deposition operation, cow also can defecate pollute pudendum and spermatic gun head; (2) easily water, disinfectant, dirt are brought into vagina in cleaning process, can make dirt, disinfectant enter the uterus during semen deposition, dirt contains a large amount of antibacterials, can infect the uterus, and disinfectant can kill sperm, directly affects smart ovum combination, and reduces conception rate.
This utility model adopts anti-pollution overcoat, save the step of the cleaning cow pudendum in the cattle artificial insemination operation, reduce vaginal orifice fecal pollution thing to murdering of sperm and importing into of vagina, because what anti-pollution overcoat adopted is the polypropylene body, its poor thermal conductivity can reduce the stimulation to the milch cow vagina, thereby alleviate the Cervical anxiety of cow, be conducive to spermatic gun and enter the cervix uteri deep, alleviate the injury of vaginal mucosa and the generation of genital diseases, reach the purpose that improves conception rate.
This utility model 2010 to 2011, apply the second cattle farm of three dairy industry companies, milk cattle cultivating residential quarter, Qingzhen and Wudang District milk cattle cultivating residential quarter in the Guiyang, the employing technical solutions of the utility model are carried out artificial insemination to the milch cow of above-mentioned cattle farm, and the situation after will inseminating is carried out record, the sickness rate of the non-return rate in 2010,2011 of statistical test cows, year over-all conception rate, breeding difficulty disease respectively, and compare with the statistical indicator in 2007,2008,2009.
Table 1 result demonstration, all lower at non-return rate, year conception rate of 2007,2008 and 2009 cows of suckling, and year by year downward trend is arranged.After adopting the technical solution of the utility model, cows all increased than front 3 years at non-return rate, year conception rate in 2010,2011, and were the trend that increases year by year.Non-return rate after the employing present technique and the average of year conception rate have improved 6.3 percentage points, 5.5 percentage points than the average before adopting respectively.Wherein, the non-return rate in 2010,2011 improved 6.4 percentage points, 9.3 percentage points respectively than 2009, and the year conception rate in 2010,2011 has improved 7.0 percentage points, 9.6 percentage points respectively than 2009.And the sickness rate reduced year by year of cows endometritis, illustrate adopt anti-pollution overcoat can reduce because of misoperation to damage and infection that the cattle reproductive system causes, both guaranteed effective combination of smart ovum, reduced again the generation of inflammation of uterus.
Owing to adopt above-mentioned technical scheme, compared with prior art, this utility model adopts the alternative cleaning and sterilizing to the cow pudendum of anti-pollution overcoat, has avoided the pollution in the artificial insemination process, reduce the generation of reproductive system disease, improved the test-tube conception rate of cattle.This utility model is simple in structure, makes easily, and result of use is desirable.
